Description

The external radiating cap encapsulating structure of resin circuit board and chip formal dress lockhole radiating block projection
(1) technical field
The utility model relates to the external radiating cap encapsulating structure of a kind of resin circuit board and chip formal dress lockhole radiating block projection.Belong to the semiconductor packaging field.
(2) background technology
The radiating mode of traditional Chip Packaging form mainly be to have adopted the Metal Substrate island of chip below as heat radiation conduction instrument or approach, and there is following not enough point in the heat radiation of this conventional package mode conduction:
1, Metal Substrate island volume is too little
The Metal Substrate island is in the conventional package form, in order to pursue the reliability safety of packaging body, nearly all adopted the Metal Substrate island to be embedded in the packaging body, and in limited packaging body, to imbed the interior pin (as shown in Figures 1 and 2) of metal of Metal Substrate island and signal, power supply conduction usefulness simultaneously, very the little so effective area on Metal Substrate island and volume just seem, and the function of the heat radiation of high heat also will be served as in the Metal Substrate island simultaneously, will seem deficiency more.
2, baried type Metal Substrate island (as shown in Figures 1 and 2)
The Metal Substrate island is in the conventional package form, in order to pursue the reliability safety of packaging body, nearly all adopted the Metal Substrate island to be embedded in the packaging body, and the Metal Substrate island is about dependence or four fine support bars in corner fix or support metal Ji Dao, also because the characteristic of this fine support bar, the heat that has caused the Metal Substrate island to be absorbed from the chip, can't conduct out from fine support bar fast, so the heat of chip can't or be transmitted to the packaging body external world fast, caused the life-span quick aging of chip even burn or burnt out.
3, Metal Substrate island exposed type (as shown in Figures 3 and 4)
Though expose on the Metal Substrate island, can provide also will good heat-sinking capability than the heat sinking function of baried type, because the volume on Metal Substrate island and area still very little in packaging body, so heat dissipation capability can be provided, still very limited.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and providing a kind of can provide heat dissipation capability the strong external radiating cap encapsulating structure of resin circuit board and chip formal dress lockhole radiating block projection.
The purpose of this utility model is achieved in that the external radiating cap encapsulating structure of a kind of resin circuit board and chip formal dress lockhole radiating block projection, include chip, the single or multiple lift resin circuit board that is carried of chip below, the wire that chip is used to the signal interconnection of single or multiple lift resin circuit board, conduction between chip and the described single or multiple lift resin circuit board or nonconducting heat conduction bonding material I and plastic-sealed body, above described chip, be provided with radiating block, this radiating block has lockhole, is equipped with conduction or nonconducting heat conduction bonding material II between this radiating block and the described chip; Be provided with radiating cap above described radiating block, protrusion is provided with a projection in the middle of the described radiating cap lower surface, and described radiating cap patches with the radiating block that has lockhole by this projection and is connected; And between this radiating cap and described radiating block and in described lockhole, be equipped with the conduction or nonconducting heat conduction bonding material III; Described radiating cap is sleeved on the plastic-sealed body.
The beneficial effects of the utility model are:
The utility model passes through addition radiating block above chip, and sets up radiating cap outside plastic-sealed body, serves as the function of the heat radiation of high heat, can provide heat dissipation capability strong, makes the heat of chip can be transmitted to the packaging body external world fast.Can be applied in and make it become height or superelevation heat radiation (High Thermal or Super High Thermal) ability on the packaging body of general packing forms and the packaging technology, can become SHT-FBP/QFN as FBP can become SHT-QFN/BGA and can become SHT-BGA/CSP and can become SHT-CSP ...Avoided the life-span quick aging of chip even burn or burnt out.
